Techno-Economic Performance Analysis of Grid-Interfaced Microgrid for Different Facilities
Abstract
This paper presents technical and economic analysis of hybrid ac microgrid (MG). The MG comprises conventional source like diesel generator (DiGen), renewable energy source such as roof-top solar photo-voltaic (PV) installation and battery energy storage system (BESS). The primary objective of this analysis is to study and compare levelised cost-of-energy (LCoE) and net-present value (NPV) for blend of energy sources catering electrical energy to various set-ups along with other vital economic instruments like internal rate of return(IRR), return on investment(ROI) and simple payback period(SPP). The analysis has been performed with existing utility-grid in operation. In order to compare the combination of micro-sources, same average annual electricity consumption has been considered as reference for comparison for various load profiles, viz. academic institutional, residential pocket, commercial, community and small/medium industrial loads. Moreover, the two tariff structures, with grid selling and non-grid selling are considered. The model has been developed in HOMER application software. The reference location for academic institution selected for study is situated in southern part of Gujarat, India and has longitude and 21.17°N latitude of 72.83°E.
